I’m wondering about that little appendage that’s coming out, what’s that and what’s it doing? Seems to be going away from the light. I tried to google but most result for my searches were just offers to buy a new cactus
Aerial roots. Your cactus might think it’s not getting enough sunlight:

Awesome find!
You may [be] the expert diagnostician we were looking for, the cactus horticulturist!
What species or type of cacti is it?
Did you change when you water, move locations, or anything that may have an impact on its health?
Not too sure either, but the more info the better.
Then more research to be done, so as to figure possible conditions ot causes!
We need House M.D., an expert diagnostician… but in this case a cactus doctor, cactus horticulturist.
